Use With a DTX-1

As of Software Version 201710081, the Portsdown software can be used to transmit MPEG-2 or H264 encoded pictures with a DTX-1. This experimental capability is NOT compatible with the use of WaveShare touchscreen and must be controlled from the Console or an Element 14 7 inch touchscreen. If you select DTX-1 as the output mode with a Waveshare touchscreen connected, the touchscreen will become unusable as soon as you got to transmit, as some of the pins used for the screen are the same as those used for sending signals to the DTX-1.
